Treasure the Severn

Join Our MGO Oyster Team

Severn River Association joined with the Department of Natural Resources (DNR) and the Oyster Recovery Partnership (ORP) to create an army of volunteer oyster growers on the Severn River.

The MGO program will help harness the cleaning power of the oyster – each mature oyster can filter up to 50 gallons of water a day — to rebuild our Severn River fishery and oyster reefs and ensure that our river and creeks are always safe to swim in.
